Question

question 6
a population of chickens consistently exhibits ratios of offspring where 75% (3/4) of chickens have red feathers, and 25% (1/4) of chickens have white feathers. what does this indicate about the allele for white feathers?
a white feathers are being dyed to make them red
b white feathers are dominant
c white feathers are homologous
d white feathers are recessive

Explanation:

According to Mendel's laws of inheritance, when a trait appears in a smaller proportion (such as 25% here) in the offspring of a population with consistent ratios, it is likely a recessive trait. Dominant traits would be more prevalent (like the 75% red - feathered chickens here). Option A is not a genetic explanation. Option B is incorrect as dominant traits would show in a higher proportion. Option C (homologous refers to similar structures in different species in an evolutionary context, not relevant here).

Answer:

D. white feathers are recessive
